Global birth canal variation gives insight into human evolutionary past and modern obstetric practices

  A recent examination of pelvises from human skeletons indicate migration patterns and climate may be responsible for global variation in birth canal size and shape. This variation likely represents neutral evolution by random chance and not necessarily the selection for pelvic adaptations, challenging long-held theories for human evolution and modern obstetric protocols. You might … Continue reading Global birth canal variation gives insight into human evolutionary past and modern obstetric practices
